Repository to host the Docker images files used in conda-forge

It can be useful to build and test these images locally. For many images this can be done by running docker build from the root-level of this repo and passing in the path to the Dockerfile that you wish to build. For example:

docker build --rm --build-arg CENTOS_VER=6 -f linux-anvil-comp7/Dockerfile .

However, certain images, such as those building CUDA, will need to have environment variables passed in to be able to build. In this case, you will want to use a command similar to the following:

docker build --rm --build-arg CENTOS_VER=6 --build-arg CUDA_VER=10.2 -f linux-anvil-cuda/Dockerfile .

• $CUDA_VER: This is the cuda & cudatoolkit version that will be used. The value of this variable should be in major-minor for, e.g. 9.2.
• CENTOS_VER: This is version of CentOS that the image should be built with. This is the major-only version number, e.g. 6 or 7. You'll usually want to build with the lowest working value for maximum compatibility.
